Brief description
A study of the impact of the nitrification inhibitors nitrapryin on nitrous oxide emissions from dairy cow urine and emissions for diary cow dung was conducted at Terang in south-western Victoria, Australia from 19 September 2013 - 21 May 2014. Experimental design was (4 treatments by 6 replicates) for soil sampling and two replicates of the 4 treatments for emissions measurement (Nil addition, Urine @1000 kg N/ha, Urine @1000 kg N/ha plus nitrapryin surface applied, dung @ 448 kg N/ha). Measurement system used automated chambers liked to a Fourier Transform infrared spectometer for gas analysis. Daily flux (g N2O-N/ha/day) was calculated for each chamber. Soil water (surface 0-65 mm) and soil temperature (50mm) was measured continuously in each chamber base. Soil mineral N content of all treatment and replicates was measured (0-100 mm) routinely. Initial site soil physical and chemical status were defined. Standard meteorological information was collected for an on-site weather station. Subjects
